Job Responsibility
Job Responsibility
  • Incident Response: Drive work investigating complex technical and process issues on a global scale spanning multiple reliability, security, and continuity disciplines for infrastructure spanning thousands of locations during major incidents/site events on edge, caching, and network infrastructure. This will require you to work closely and effectively with a variety of cross functional teams, managed service providers, and third-party vendor partners
  • Escalation Management: Participate in the global team’s Tier 3 and 4 on-call rotation with the goal of routing issues as needed and understanding how processes or tooling might be improved, skills can be developed, or automation can be implemented to prevent the need to escalate similar issues in the future
  • Operational Leadership: As an operations practitioner within the team you will be expected to drive improvement in everything we do. In this role you will indirectly manage the activities of a large contingent workforce responsible for delivering road mapped projects and executing on recurring activities. You will drive standards across the network and ensure that we are fully compliant to those standards and policies
  • Risk Management and Assurance: Work internally and with upstream partner teams to ensure design, build, and operations aligns to applicable reliability, security, privacy, regulatory policy, and business continuity drivers
  • Information and Data Assurance: ensure relevant operational process, procedure, and policy documentation is effectively managed and the data required to support operations is complete and accurate in systems
  • Automation: Be heavily involved in driving the team to analyze operational events in order to identify new automation opportunities and help us achieve our goal of all faults in the network being fully remediated by software. This will include helping others understand our requirements and drive their roadmaps, but may include directly implementing light weight solutions in code
  • Data Measurement: As an operations practitioner supporting our network, you will be expected to drive quality into the metrics we report to assist us in focusing on the areas that give us the best return on investment. This could include measurement and analysis of our escalation issues, fault/event trends, infrastructure capacity, and vendor performance failures
  • Collaboration and Partnership: You will work closely on supporting our internal customers (Network Engineering, Systems Engineering, Traffic, Logistics, Program Management) and vendors (IT asset disposal, and Hardware partners) and ensuring that their needs and issues are being addressed proactively across global sites
  • Roadmap Ownership and Strategy: Own the planning and execution of an organizational-level roadmap and strategy to deliver business outcomes
  • Technical Leadership: Provide root cause analysis and corrective action leadership to resolve all operational issues found across edge and backbone architectures and hardware platforms. You will be integral to identifying problems and implementing effective solutions across highly cross-functional infrastructure teams to include network engineering, logistics, supply chain, compliance, legal, software system engineering, and program management to scale with the rapid expansion of the Meta platform and customer base
